Explain Why Socialising Drains You Even When You Enjoyed It

You had a genuinely good time and you're still lying on the sofa afterwards feeling wrung out. This explains the actual difference between enjoying an interaction and finding it effortful, what usually causes the effortful kind, and why that's not quite the same thing as simply being an introvert. Ends with a question to pin down your specific drain.

Explain why someone can genuinely enjoy an evening with friends and still come home completely drained by it, rather than energised. Cover the difference between enjoying an interaction and finding it effortful, what typically causes the effortful kind (constant social monitoring, performing rather than being, group size, noise, or something else), and how this differs from simply being an introvert. Keep the explanation to around 200 words in plain language, and end with one question the person could ask themselves after their next social event to identify their own specific drain.
